Post-release of 2.1.1 — silence loader-discovery WARNING spam for apps.

  • list_instruments() is quiet by contract: expected loader-probe skips log at DEBUG; the scan uses create_all(quiet=True) so apps no longer see WARNING:root: Could not create loader … on every call. (#786)

cellpy - cellpy 2.1.1.post2

Post-release of v2.1.1 — collected summary facet y-axis controls for apps. Safe drop-in over 2.1.1 / 2.1.1.post1.

  • Per-panel y-limits (and clearer share_y) for collected summary facet plots (#804).

Summary facets default to independent y-scales; pin CE (etc.) with Collection.plot(y_ranges={"coulombic_efficiency": [0, 110]}) (Plotly).

cellpy - cellpy 2.1.1.post1

  • Backfilled HISTORY.md for the already-shipped 2.1.1 and 2.1.0.post1 releases (#802).

No code behaviour change.

cellpy - cellpy 2.1.1

Patch release — app-builder fixes and conveniences (gathered while building cellpy-simple-gui on 2.1.0.post1). Additive, no breaking changes.

Fix

  • Group-averaged collected summaries now plot: Collection.plot() / plot(spread=True) render group-keyed mean±std frames instead of raising KeyError 'cell' (#785).

Collect / batch

  • cellpy.collect.from_cells() (+ Batch.from_cells): build a batch straight from already-loaded CellpyCell objects held in memory (#787).
  • Collection.is_grouped / meta.grouped: signals whether group-averaging actually happened (#790).
  • Collection.save() now supports xlsx and json (was parquet/csv only) (#789).
  • CurveOptions gains mode / method, forwarded per cell to get_cap — parity with the single-cell call (#788).

Instruments / docs

  • cellpy.list_instruments(): quiet, app-facing instrument listing → [{"id", "label", "models", "suffixes"}], no per-module warnings (#786).
  • App/agents guide: note on the polars/pandas frame boundary and quieting cellpy's logger/warnings (#791).

Deferred app-builder ideas split to v2.2: lightweight read_meta (#799), per-instrument metadata schema (#800), app-friendly collected-figure theming (#801).

cellpy - cellpy 2.1.0.post1

Post-release of v2.1.0 — docs-only, no code behaviour change. Safe drop-in over 2.1.0.

  • Stripped issue-tracker references (#NNN, cellpy-core#NNN, epic/decision/Stage codes) and "what it used to be, in which issue" migration narrative out of package docstrings across 100 modules, so the API reference reads cleanly (#771).
  • Documented the Read the Docs header release-badge behaviour — it always shows the live GitHub latest release; the RTD version switcher is the source of truth (#776).

No API, schema, or runtime changes.

cellpy 2.0.0

Stable cellpy 2.0: native headers, v9 zip-of-parquet cellpy files (v8 HDF5 still readable), cellpycore==0.2.4.

Soak: v2.0.0rc1, v2.0.0rc2.

Support

  • Python ≥3.13
  • The v1.x line is bugfix-only for 12 months from this release date (decision #438-6)

Known limitation

cellpy 2.0.0rc1

First release candidate for cellpy 2.0 after the native-headers / polars flip (alphas through v2.0.0a5+).

Gates (#574)

  • CI essential (linux / uv) and full (linux / uv) green on the release tip
  • Docs (zensical) green
  • Benchmarks vs GHA v1.x baseline: fail-band (+100%) clear; intermittent load/summary warn-band (+20%) accepted for rc soak as single-round GHA noise
  • cellpycore==0.2.3; migration guide + DEPRECATIONS.md present
  • Stage-3 sub-issues closed except tracking; #655 (fixture gaps) deferred

Install

pip install --pre cellpy==2.0.0rc1

Not in this release

  • Stable v2.0.0 (after soak)
  • conda-forge feedstock bump (follows stable)
  • Start of the 12-month v1.x bugfix-only window (starts at stable)

1.1.0.post2

  • Fix: lazy config load pushes .env_cellpy into os.environ so OtherPath SSH auth works again after #453. (#662)
  • Docs: warn that cellpy 1.x is maintained until July 2027 (#513).
  • Release: allow v1.* tags from the v1.x maintenance branch (as well as master).

cellpy - cellpy 2.0.0a5 — native-headers flip

Fifth cellpy 2 alpha. This release lands the native-headers flip: cellpy 2's runtime now speaks native cellpycore column names end to end — no legacy rename sandwich.

Highlights

  • Default runtime is native (CellpyCell(native_schema=True)): from_raw/load → make_step_table → make_summary → save all run on native column names via the polars engine.
  • Legacy compatibility preserved:
    • Legacy header attribute access (headers_normal.voltage_txt, …) is carried by a deprecation-warned shim.
    • native_schema=False keeps the full legacy bridge for v8 byte round-trips.
    • Legacy v8 files still load, and save(format="v8") still writes them, via to_legacy/to_native.
  • Native merge() (campaign + continuation) works on the default path.
  • Value-parity oracle: the native and legacy pipelines are asserted equal on 125 mapped columns (raw/steps/summary, incl. IR and CE) on the canonical dataset.

Breaking changes (alpha)

  • data.raw / data.steps / data.summary now carry native column names by default (e.g. potential, cycle_num, datapoint_num, step_type). Access via the header objects (shim-carried) or migrate literals to native names. Set native_schema=False for the legacy names.
  • get_cap curve frames use native CurveCols (potential/capacity/cycle_num/direction).
  • cellpy.utils.easyplot removed (deprecated since 1.1).

Known gaps (tracked, xfailed)

  • Native summary does not yet compute shifted_* capacity, RIC, or cumulated_coulombic_efficiency (#552).
  • Native step_specifications application + exclude_step_types value parity to verify (#554).

Pinned to cellpycore==0.2.2.
